Phase conversions in neutron stars: Implications for stellar stability and gravitational wave astrophysics

G Lugones, AG Grunfeld - Universe, 2021 - mdpi.com
We review the properties of hybrid stars with a quark matter core and a hadronic mantle,
focusing on the role of key micro-physical properties such as the quark/hadron surface and …

Delta baryons and diquark formation in the cores of neutron stars

G Malfatti, MG Orsaria, IF Ranea-Sandoval… - Physical Review D, 2020 - APS
We investigate the hadron-quark phase transition in cold neutron stars in light of (i) the
observed limits on the maximum-mass of heavy pulsars,(ii) constraints on the tidal properties …

Hybrid stars are compatible with recent astrophysical observations

A Kumar, VB Thapa, M Sinha - Physical Review D, 2023 - APS
Compact stars (CS) are stellar remnants of massive stars. Inside CSs the density is so high
that matter is in subatomic form composed of nucleons. With an increase of density of matter …

Vector interactions inhibit quark-hadron mixed phases in neutron stars

G Lugones, AG Grunfeld - Physical Review D, 2021 - APS
We investigate the surface tension σ and the curvature energy γ of quark matter drops in the
MIT bag model with vector interactions. Finite size corrections to the density of states are …

Constraining strangeness in dense matter with GW170817

RO Gomes, P Char, S Schramm - The Astrophysical Journal, 2019 - iopscience.iop.org
Particles with strangeness content are predicted to populate dense matter, modifying the
equation of state of matter inside neutron stars as well as their structure and evolution. In this …

The first direct detection of gravitational waves has opened a new window to study the
Universe and would probably start a new era: the gravitational wave Astronomy …

Detailed analysis of the special points on solutions of hybrid/twin stars

D Sen, N Alam, G Chaudhuri - Physical Review D, 2022 - APS
Hadron-quark phase transition in neutron star cores is achieved in the present work with the
help of the Maxwell construction. For this purpose, we employ six different and well-known …

Hadron-quark mixed phase in the quark-meson coupling model

M Ju, X Wu, F Ji, J Hu, H Shen - Physical Review C, 2021 - APS
We explore the possibility of a structured hadron-quark mixed phase forming in the interior of
neutron stars. The quark-meson coupling (QMC) model, which explicitly incorporates the …

Nuclear symmetry energy and hadron-quark mixed phase in neutron stars

XH Wu, H Shen - Physical Review C, 2019 - APS
We study the hadron-quark mixed phase, which may occur in the interior of neutron stars.
The relativistic mean-field model is employed to describe the hadronic phase, while the …
